Hello together, I tried capturing the milky way a few says ago. This isn't my first time doing astrophotography but I ran into a problem. I captured 128 light frames, 51 darks and +100 flat and bias frames. I loaded them into DSS and registered them. Firstly I set the threshold so that ~200 stars were found. All pictures have a very similar score (1070-1400) and number of stars (180-220). There were no clouds. After the first stack the result looked horrible. I looked at the offset data and some images got rotated by over 150 degrees which can't be since all pictures were taken within an hour. Some pictures did't have any offset information at all (NC)! I changed the star detection threshold and tried everything from 15 to 500 stars with the same result. I looked a bit closer which stars got detected and this seems kind of random. The stars that got recognized are not even similar in 2 pictures taken after each other. What else can I try? I used the Sony A7iii with the Samyang (Rokinon) 14mm f/2.8. It was my first night with the 14mm. I stacked a set of images of the Pleiades a few weeks ago with no problems at all (Sony a7iii, Tamron 70-180mm f/2.8). Converting the raw images into DNG didn't fix the issue. Thanks! DSC02847.tif

Not sure what topic to put this in but I've been struggling with deep sky stacker, because of my optlong ccd light pollution filter most nebulas come out one shade of red, for example the Monkey's head nebula, see attached example. Dumbell and ring turned out as seen online and Stellarium. All 3 images were taken with a rct f/8 and a canon 600DA. I've never tried these objects without the filter as I got new equipment and this is the most active I've been in my hobby for many years. I'm not spending hundreds or thousands on software so preferably if i can get the correct colour on these with dss or some other free/semi free software that would be great. Thanks

It was the first time last night I used imaging software to capture deep sky objects, it was also the first time using a camera connected to a laptop. I was so amazed by the quality i was capturing. Until I went back and found that i couldn't view my pictures, but in N.I.N.A I could see them clear as day. I really hope I haven't lost these or I'd be heartbroken! Below is a 3min sub, I did 20 of these, but loading them into Depp Sky Stacker shocked me as they turned out grayscale and you could only see a dozen stars. The image files are fit's which i can't even view at all now, never used that format and I'm not using it again if it ruins my images, what's the actual point on that!? How do I fix this? I may have to use a different processor, i've been using dss for years

Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO. I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total. I Used DSS for alignment and stacking, then Pixinsight for LRGB combination. My issue is that i'm not happy with the colours, the stars all appear white and the background is strange. I have attached the Aligned LRGB images. Can anyone point me in the right direction? Thanks! Green.TIF red.TIF Lum.TIF B.TIF

Hey everyone, Over the past few days i've been gathering data on M31 due to the battery not lasting long and andomeda dissapearing behind a tree, therefore the mulitple imaging sessions. So far i've been out and me being me, only took dark, bias and light frames for the first 2 sessions but for the last one i also included flats... (The lights all have very slightly different settings cause i have been experimenting slightly... that being 45sec @ ISO 400, 45sec @ ISO 200 and 50sec @ ISO 100) Now DSS assinged all the correct bias and dark frames to the corresponding light frames but because i only have flats for my last imaging session it applied those to all the different light frames and not just to the last set...(and due to me moving the telescope / taking the camera off, the dust spots have obviously been moving around and that therefor dont work at all for the other light frames...) So my question: Is there any way in DSS to apply flats to only one set of light frames and if not are there any other apps with which i can do this with? Many Thanks! -
Hi, I have recently changed my laptop to a Dell XPS 15 which has an i5 processor. Notably it has a combined drive ie it has 100GB Solid State Drive (C:) which is where the programs and operating system reside plus a 1TB Hard Drive (D:) for general files. I am getting error messages from DSS that there is not enough space on my C drive, it requiring on this occasion 4.5GB. Looking at the C drive it was indeed very low on free space, so I freed up some space on my C drive and got rid of that message. But when DSS ran it went through the whole process to the end and then didn't produce an image. I checked the settings and there is a path specified for the output so that is apparently set correctly. I have used DSS for many years on my old laptop, but this laptop is a problem. I think the issue lies in the combined drives. There is 1TB of space available to it on the D: drive but it doesn't seem to be able to use it. I wonder also if there is an issue with the pathway specified so that it is not 'seeing' the file allocated to it on the D: drive. I tried moving DSS folder to the D: drive and ran it from here but it still has the same issues. Has anyone come across this kind of issue? And is there a solution?

Hi is anyone using Regim to stack using a dslr modded , currently trying to work out the settings in regim , im using a modified canon 1000D , do i need to set up libraw within regim ? if anyone has good success in using regim i would be interested in hearing what settings you are using .

Hi I've taken a few images from a dark sky location of the night sky with just my Cannon camera on a fixed tripod - 1 minute frames (25 mins total). I realise these are short frames, but as I didn't have a mount with me I though 1 minute would be OK before stars started to trail. Anyway, when I try stacking the frames through DSS the images stack but show the same star multiple times as they rotate (we rotate) in the sky above. When I check stars chosen for alignment these are actually hot pixels, and I can only see one or maybe two that are actually stars. I've tried picking stars manually but the programme only allows you to turn on and off the stars that it has chosen. Is there a way to pick stars manually? Or any settings that I could change? Maybe I should be using different software? DSS has always worked for me in the past, but I've not used it for short frames through just my camera before. Any help would be appreciated

I did a test using the same stack of images, but using 5 different stack modes in deep sky stacker... which one is best? I just did very minimal adjustments to them and they all have the same....align rgb, and adjust exposure.... this is a stack of 26 min 30 sec........ 106*15 lights, no darks no flats no bias,,,,,,iso=3200 f7.1 on 50 mm lens........... If someone would like to process them and see what you get out of them that would be great....... I cant really see too much of a difference between the different stack modes All of them have the same file size except the first one the avg stack mode,,,it is smaller.... 2 other stack modes auto adaptive and maximum stack didn't work avg stack modecopy.TIF entropy weighted avg stackcopy.TIF kappa sigma clipping stack modecopy.TIF median kappa sigma stackcopy.TIF median stack modecopy.TIF -
Running DSS v 3.3.2 on win7 machine. Calculating master frames before processing all the lights (one light added to the mix to enable the program to calculate the masters). Master bias, dark & darkflat produced successfully.

Hi! I did an imaging run on the Flame/Horsehead Nebulae last night, and I got about 2 hours of data. About 20 minutes worth are with my hydrogen alpha filter. To my dismay, when I went in to stack my subframes on DSS, I get a message saying that only one out of my 52 frames will be stacked. I've been tinkering with the settings today, but I'm not sure if the problem lies with my DSS settings or with the frames. These were the first i've taken at ISO 800, so I'm worried that my stars may be a little too big/burnt out for DSS to actually recognize them as stars. Perhaps I haven't focused well enough? I think that's a distinct possibility with my hydrogen alpha frames. I did use my trusty Bahtinov mask, so I hope I didn't goof on that! Anyway, I'm including some representative subframes if you'd like to take a look. I'm taking the average for the subframes and calibration frames)

Evening all, I've been trying to get to grips with stacking images and think I have sort-of figured out how to do the calibration images as well as the lights. However, as I read through these forums, I'm seeing lots of references to people successfully stacking lights that have been made up of various different timed exposures. I seem to have fallen under the impression that all the light images need to be of identical parameters. I've even tried experimenting with deep sky stacker using lights with different parameters and DSS always rejects them ( I end up with the "only one frame will be stacked" error. Appreciate any insight on this - thanks

I have a few queries re tiff files in DSS and hope someone can explain. Firstly, it took me forever to figure out that the autosave tiff file cannot be opened using normal editing software because its 32 bit. At least I think that is the case – maybe someone could kindly confirm. Second, when the final image is rendered on the screen, it seems to be quite dark. Of course this can be edited within DSS, and I’ve found stacking the RGB curves somewhere in the middle of the graph seems to get a good result. So then I save this file as a 16 bit image, and play with it in editing app. That works OK. But if I close the image in DSS and then re-open the 32 bit autosave file, it looks quite different to the way it was originally rendered. I also notice that the graph now looks like a straight line, rather than the original curvy line. If I hit the “reset” button, the curve appears as it did in the original, and if applied, the image then darkens to the same appearance it had in the original. I don’t know why this should be, but the key question is, if I reopen the 32bit autosave file, will this have the same data as the original? Or do I need to do all my DSS manipulation before closing the original file? I hope that makes sense! Thanks for reading.

I have a problem with stacking images from my 5D MK3, the files are huge, I’ve tried both- Astroart V5 and DSS, Astroart fails to stack the CR2’s because of a memory issue? Deep sky stacker gets there in the end but the colour is washed out and no amount of tweaking can get an acceptable result. Pixinsight – er well it’s so long winded I cannot for the life of me understand it; I suppose I would have to batch convert all the .CR2 files into .Fits then process .. am I correct? Any thoughts?
